IMPROVEMENT IN TUCK-MARKERSFOR SEWING-MACH! I Specification forming part ofLetters Patent No. 138,635, dated May 6,1873; applica October 5, 1872.

To all whom it may concern:

Be it known that I, HARRY G. GooDRIoH, of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Tuck-Markers for Sewing-Machines, of which the following is a full description, reference being had to the accompanying drawing making a part of this specification, in Which- Figure l is a plan; Figs. 2,3, 4, and 5, details. Fig. 2 represents the device as seen from the point 00; Fig. 3, the end as seen from the point y,- and Fig. 4, as seen from .2; and Fig. 6, a variation.

In the drawing, Arepresents a plate of sheetmetal with which the other parts are connected B, sliding gage held in place by the thumbscrew to; b, slot to receive the thumb-screw by means of which the tucker is attached to the machine 0, spring arm; D, spring clothsinoother, to which a portion of the creasing devices are secured; 0, long tongue, which may be secured at the end and to the under side of D d, tongue secured at the end and to the upper side of D, and curved upward, as shown in Fig. 3; f, slit cut in the plate A; and e, a part of the plate 0b, curved upward, as shown in Figs. 2 and 4. This part 6 may be made of aseparate piece connected to A.

The relative position of the parts 0, cl, and e is represented in plan in Fig. 5, (I being dot ted in.

In use the cloth to be creased is passed over the tongue 0, under 01, then down under the tongue 0, and, there being a little space vertically between 0 and the end of e, the spring-arm 0, when brought down, will press down the tongue cl upon the end of e, holding the cloth ICE.

at that point firmly between at I c,- then, as the spring-arm descends still f ther, it will carry down 01 and e, and the 010 l between 0 and 0 will be bent over into a very narrow fold, forming a well-defined crease. l

The special office of cl is to car down 0 and keep the cloth down upon the p a te A or. the bed of the machine. i

Where the bedof the machin is perfectly level it is not necessary to exten the plate A under the tongue 0.

The parts 0, d, and 0 should be or other suitable spring metal.

I make the tongues c and d a I e-presented, but there are various ways in wh h e, or some thing which answers its purpos ell, may be made, one form of which is repre nted in Fig. 6, in which 9 takes the place of I prefer to make the marker ubstantially as at first described, rather tha as shown in Fig. 6, because the tongue e, w 11 located as described, has a greater tende as it descends, to fold the cloth over upo 0 than when made as shown in Fig. 6.

Thet'orm of the plateAand the loth-smoother D is not essential; any piece f metal suitable to support the parts connect I with A and D may be used.

What I claim as new is as fol ws:

The combination of the ton j ues c d and spring-arm D with the lip or t ngue 6, plate A, and arm or hammer 0, all 0 crating substantially as and for the purpos s specified. H. 0. G O'DBIOH.
